Application filed May 7, 1914. Serial No. 836,994.

To all whom it may concern Be it known that 1, PETER E. MCSWEENEY,

a citizen of the United States, residing at I specification'and claims.

' a device which is simple and durable in con- Springfield, in the county of Greene and State of Missouri, have invented certain new and useful Improvements in Triple-Valve- Grinding Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and-useful improvements in grinding machines and more particularly to a triple valve grinding machine and the primary object of the invention is to provide an improved machine of this character which will grind a plurality of valves at one and the same time, the valves being of various heights and designs.

Still another object of the invention re-- sides in providing a machine which will permit the valves which are to'beground to be positioned vertically on the'machine so'that' the oil and other matter which is received in the valve members will not accumulate in any one portion thereof but pass completely therethrough.

. A still further object resides in providing inexpensive to struction, comparatively manufacture and one which will -be very from the other for the longitudinal length eflicient and useful in operation.

With these and other objects in view my invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the In the accompanying part of this application: Figure 1 is a front elevation of the machine. Fig. 2 is a side elevation thereof. Fig. 3 is a plan view of the same. section therethrough as seen on line M, Fig. 3.

In describing the invention 1 shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views and in which- 1 indicates a base or support such as the bed of a lathe or the like upon which are mounted in spaced relation to one another a pair of brackets 2 the upper ends thereof supporting bearings 3 in which is rotatably mounted a drive shaft 4. This shaft 4 is of the crank shaft design, and has a drive drawings forming a Fig. 4 is a vertical transverse If, however, it is desired, the motor such as is often used on electric lathes may be connected directly to the shaft 4. Also mounted on the base or supporting member 1 in a plane-forward of the plane of'the sup ports or brackets 2 and in planes beyond the latter are the additional brackets 6 the latter extending upwardly to a plane somedistance above the upper ends of the brackets 2.. The upper portions of these brackets support bearings 7 in which isrotatably mounted a shaft 8. Adjustably connected on this shaft 8 is an arm 9 forming a crank thereon the same extending rearwardly over the shaft 4 and the rear end of said arm 9 i has connection with a pitm'an 10 which also connects with the crank on said shaft 4. It

will thus be seen that upon the rotation of the shaft-4, the shaft 8 will be oscillated in its bearings and a balancing weight 11 is provided on the cranka-rmB to aid in the actuation of the latter.

Supported on the base 1 and arranged in a plane above the plane of the upperface of the latter is a stationary table 12, the same being supported by means of brackets 13. The table 12 is provided adjacent its inner edge with a plurality (four in number) of openings the same being spaced one points on the shaft 8 are the outstanding arms 16, to the outer ends of which are adjustably secured the clamping members or the like 17. Pivotally connected to the clamping -members are the upper ends of links 18 the opposite ends of said linksbeing pivotally connected respectively to the upper ends of said sliding or reciprocating rods or arms 15. It will thus be seen from this construction that upon the oscillation of the shaft 8 in its bearings, the slide rods 15 will be reciprocated in their respective bearings 14 to carry out the object of the device as will be hereinafter and more particularly set forth. The stationary table 12 is also provided adjacent its forward edge and in alinement with the openings adjacent;

the rear edge thereof with additional openings indicated as 19 in the drawings and theupper face of this table surrounding the openings is offset to provide seats 20.

which receive master chucks 21- therein. These master chuckc 21 are held in place in the seats or recesses by means of the adjustable clamping members 22 which are carried on the upper face of the table 12 as clearly shown in the drawings, and the triple valves are adapted to be threaded into engagement with these chucks whereby to permit the same to be properly ground,

which is the primary object of the device.

Adjustably secured to the reciprocating arm 15 at predetermined points thereon above and below the table 12 are the additional outstanding and forwardly projecting arms 23 and 24 respectively. Suitably engaged with the outer ends of the lower arms 24 are the adjusting screws 25 while.

adjustably secured to the outer ends of the upper arms 23 are the vertically extending rods or arms 26 and these screws 25 and the arms 26 are adapted tov be adjusted so as to securely retain therebetween the pistonsv of the triple valves when the latter are properly seated on the table, it being understood that the pistons of said valves operate through the openings 19 in said table 12. Through this medium, it will be seen that the pistons of the triple valves will be reciprocated in the latter and the desired grinding of said valves will result therefrom.

When triple valves of an air brake system become defective, the same are removed and the triple valve pistons are removed from the valve body by removing the cylinder cap from the latter. The slide valve and packing ring are then removed from the.

triple valve piston and said slide valve placed on a face plate upon which fine emory has been sprinkled and through this medium the slide valve is faced off. The valve seat bush which has a groove therein for the reception of the slide valve is then faced with 'asafety' parallel file. A new packing ring is'then fitted snugly to the packing ring bush and the latter replaced in. position- The slide valve is then replaced on grinding of the various parts of the triple valve, a well known type of Westinghouse triple valve is assumed'to be in use. Inthe use of. other forms and styles of triple valves, the operation is quite' similar and the principle the same.

,From the foregoing it will be seen that'I have provided a simple, inexpensive and eificient means for carrying out the objects of the invention, and while I have particularly described the elementsbest adapted to perform the functions set forth, it is obvious that various changes. in form, proportion and in the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the principles of the invention.
